摘要
由等式[x_3x_1x_2=x_3x_1x_2x_3x_2x_1x_2]定义的左半正则带簇是带簇的一个重要的真子簇,现有文献已用2个禁止子半群对其进行了刻画。在此基础上,用相关的禁止子半群刻画了带簇的一个新的真子簇[x_4x_2x_1x_3=x_4x_2x_1x_3x_4x_2x_3x_2x_1x_3]。
The left semiregular band variety defined by the equation [x3x1x2=x3x1x2x3x2x1x2] is an important proper subvariety of band variety. The variety is described in terms of two prohibited subsemigroups by the existing literature. Based on that, a new proper subvariety [x4x2x1x3=x4x2x1x3x4x2x3x2x1x3] of band varieties is characterized by relevant prohibited subsemigroups.
